For Ruby, we have irb. For Python, we have IDLE. For Javascript, is Firebug or Chrome on a blank page the best way to run or test Javascript interactively?
What is it? The JavaScript functions that allow you to make interactive web pages. Why should I learn it? Your HTML pages need JavaScript to become more interactive.
JavaScript is a programming language we can use to make a website interactive. When we search something on Google or click a link, our website changes — that's what JavaScript allows us to do. First, we'll use Sublime to create an index.
You can run JavaScript console in terminal or any command-line interface using Node. js, an open-source, platform-agnostic runtime that executes JavaScript outside a web browser.
To execute JavaScript in a browser you have two options — either put it inside a script element anywhere inside an HTML document, or put it inside an external JavaScript file (with a . js extension) and then reference that file inside the HTML document using an empty script element with a src attribute.
You can also visit JSBin or JSFiddle.
On the iPhone, there is JSanywhere (it seems written by a Japanese author).
There is not much information about it on Google in English, but it can be downloaded for free from the App Store.
